Inspections Before & During EVERY lift: visual examination must be performed by the operator prior to
AND during each lift. In particular, the operator should inspect for:
1. Debris on the load surfaces; AND
2. Condition and operation of the controls.
Frequent Inspections
: the specific meaning of “frequent” varies from daily to monthly depending on the
service classification (normal, heavy, severe, and special/infrequent) of the pipe grab. Definitions of the
service classifications appear in ASME B30.20. The operator or other designated person(s) should
visually inspect the pipe grab for:
1. Deformation, cracking, or excessive wear of any part of the pipe grab;
2. Operating mechanisms for conditions that interfere with proper function; AND/OR
3. Loose or missing fasteners, stops or nameplates.
Periodic Inspections
: complete visual inspections performed AND recorded by a qualified person. The
inspection should specifically look for:
1. Loose bolts or fasteners;
2. Excessive wear of friction pads, linkages, and other mechanical parts; AND/OR
3. Excessive wear at the points where the grab connects to the hoist hook, and load support
clevises or pins.
Maintenance: the end-user must implement a maintenance program to ensure the proper function and
safety of the pipe grab. A qualified person may establish a program that is used in preference to the
maintenance procedures described below. However, if you apply the procedure below, complete EVERY
step each time
maintenance is performed.
ONLY qualified persons may perform maintenance on the pipe grab. A qualified person
is someone “who, by possession of a recognized degree in an applicable field or certificate of
professional training, and experience, has successfully demonstrated the ability to solve or resolve
problems relating to the subject matter and work.” See ASME B30.20-0.2-2003.
Step 1
: All sources of power must be disconnected, locked out and tagged, “Out of Service.”
Step 2
: Disconnect the pipe grab from the hoist hook, and tag it as, “Out of Service.”
Step 3
: Perform all adjustments identified as necessary during any inspection (every lift, frequent, or
periodic). Refer to ASME B30.20 for recommended inspection procedures.
Step 4
: If the inspection identified conditions which require new parts to repair, contact Vestil to order
replacement parts. Deformity, corrosion, rusting, or excessive wear of fasteners, jaws, pipe guide
weldments, or the clevis warrants immediate replacement of the affected part(s).
The reader should understand the significant difference between “Adjustments [and]
repairs,” and modifications. An adjustment or repair is a simple correction that restores the grab to
normal operating condition, such as tightening loose fasteners, or removing debris from the surface of the
grab. A modification is a change that alters the grab from normal operating condition, like bending the
structural members or removing the pipe guide weldments. NEVER modify the pipe grab without the
express, written approval of Vestil. Modifications may render the pipe grab unsafe to use.
DO NOT use the pipe grab if adjustments and/or repairs are incomplete! Return the grab to service
ONLY after finishing all necessary repairs and/or adjustments.
Step 5
: Install the replacement parts.
ASME B30.20 requires special markings for all repaired or modified lifters (pipe grab).
Consult the standard and affix/attach the necessary marking(s).
Step 6
: After the grab has been repaired, conduct a periodic inspection. The grab may be returned to
service ONLY IF the grab passes the inspection. Repeat steps 3-5 if the inspection reveals additional
issues.
Step 7
: Make a dated record of the repairs, adjustments and/or replacements made.
